IMPROVEMENT IN WINDILIILLS.

TO ALL WHOM IT MAY CONCERN: l

Be it known that I, WALTER Pneu, of'Rockford, inthe county of Winnebago, and State of Illinois, have invented certain new and useful ImprovementsA in Windmills; and I do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, making a part of thisspeciiication, in which- Figure 1 is a side view ofthe mill.

Figure 2 is a front view.

Figure 3 a top view.

Like letters of referenccrefer to like parts in the different views.

. .In fig. I, A is a pest, standing upon a platform, B, at one side of the well. To this post is pivoted th`l pump-handle D, between the cheeks of the stay C, g. 2, and which is operated by the following-described machinery, viz On the top of the post A is mounted the tubular shaft E, which is supported in a vertical position by the supplementary post F, by acollar, F', and which post is secured to a platform or arm, G. The

lower end of the shaft is placed in a band or collar, H, in which it revolves, and is withheld from displacement.'

To the upper end of the shaft is secured a pair of arms, I, between which plies the crank I'. On the projecting end of the crank-shaft J is secured a pair of disks, J', between which the four varms K are firmly fixed, and to which arms are loosely hung the wings or sails K'. On the .shaft J is an adjustable collar, L, which is connected to the wings by links L', and also to the'angular lever M, by the links M', and yoke N which is iitted loosely to the collar L, in u groove provided for that purpose.

The vane of this mill consists of the arms O, bolted or otherwise secured to the shaft and arms I, in the O' is the sail by which the mill is veercd around by the changing winds. P is a small auxiliary mill or wings, the purpose of which is to check the motion of the larger mill during strong winds, and thereby prevent accident to the mill by any accelerated motion, and which is accom.A plished as follows: One end of a cord or strap is attached to the shaft of the small wheel, and the other to the lower end of the lin-k S. New, if the wind blows hard, the rope will wind upon the'shaft, and thereby lift up the link and weight, which boing connected to the large wheel, by th'e intervention of the lever M and link M', will canse the fans to turn more or less edgcwise to the wind, and thus check its speed. Y

Having thus far described the several parts of the mill, the operation of the same is as follows: P' is a pitlnan, by which the handle D, above referred to, is connected to the crank I', by a ball-and-socket joint, Q, fig. 1. As the crank is turned by the revolving arms ofthe mill, the handle is operated, which in turnopcratcs the pump-rod, indicated by the dotted lines Q', fig. 2 ;v the rapidity of the strokes being as the speed of the revolution ofthe mill, which may beiregulated by the governor-rod It as follows: This 'rod is connected to a yoke, R',

surrounding the tubular revolving shaft E. Upon this yoke stands the foot of the link S, the lowerend of whichA is loaded with the weight S'. On raising up this yoke or collar, by the windlass U, to whichthe r'od It is attached by thc straps U', will push up the link S, which acting on the lower arm of the angular lever M, will throw the upper arm back, and, in so doing, will carry with it the link M', by which the lever and arms of the mill are connected, by the intervention of theA adjustable collar L and links L', the eifect of which will be to cause the wings or sails of the mill to present an increased surface to 4the wind, and thus catching more wind, the revolutions will be accelerated, and hence the pump will be worked with greater rapidity and elfeot. And

so, on lowering the rod, the weight S', referred to, will cause areverse action of the lever M, and thus bring the i edge of the wings or sails ofthe mill more or less to thek wind,with a corresponding retardation in theirrrevo lutions` By this means the mill can be easily regulated to run swiftly or slowly, as circumstances may demand. Should it be required to work the pumps by hand, it is easily done by de taehing the pitman from the pumphandle, by removing the pin a, fig. 2; first, however, pushing up the rod b out of the eye of the pin, which is inserted therein for the greater security of the pin. '.lhev pump thus detached is worked in the ordinary way This mill is well adapted for other work than that of raising watcr.- It can be applied with success to run-l ning light machinery, sawing', churning, corn-mills, Svc. It is light in its structure, and yet strongly plancd and durable. It is simple in its arrangements, and free in its operations, and can be leasily taken down and removed from place to place.

Vhnt I claim as my improvement, and desire' to secure by Letters Patent, is-

1. The weighted link S, lever M and link M', as arranged, in combination with thc adjustable collar L and v links L arms and sails K K for the ur ose and in the manner as described.

i Windlass U, rod R and yoke R', in combination with the link S, as and for the purpose set forth. i 3. In combination with the above-described mill, I claim the auxiliory mill or wings P, as and for the `pursot forth. i
